I don't normally access the hardware directly, the windows API
gives me easy access to the serial port, so I don't have to worry
about what memory locations are what.

>From the Link port text file at ticalc. org:
The bits CTS/DSR can be
read from port $3F8+6, bit 4 (CTS) and bit 5 (DSR). The bits RTS/DTR is
controlled from port $3F8+4, bit 0 (DTR) and bit 1 (RTS). $3F8 is the port-
address for COM1: (or $2F8 if COM2: is used).
The document has C and Pascal example routines for sending and
receiving data.

Yes several, check the ticalc.org archives.

As plurdled gabbleblotchits on a lugrid bee.
Groop I implore thee my froonting turlingdromes
And hooptiously drangle me with crinkly bindlewurdles
Or I will rend thee in the gobberwarts with my blurglecruncheon,
See if I don't! -- "Vogon Poetry", Douglas Adams
